CA 2627999

The invention relates to a method and an apparatus for generating a depth map from a digital monoscopic color image. The method includes the following general steps: a) obtaining a first color component of the MCI, said first color component corresponding to partial color information of the MCI; and, b) assigning depth values to pixels of the MCI based on values of the first color component of respective pixels for forming the depth map for the MCI. In one embodiment, the depth values are generated by adjusting and/or scaling of pixel values of the Cr chroma component of the monoscopic source color image in the Y'CbCr color system.

La présente invention concerne une méthode et un dispositif de production d'une carte de profondeur à partir d'une image monoscopique de couleur. La méthode comprend les opérations suivantes : a) obtenir une première composante de couleur de l'interface MCI, ladite première composante de couleur correspondant à l'information de couleur partielle de l'interface MCI; b) attribution de valeurs de profondeur aux pixels de l'interface MCI, en fonction des valeurs de la première composante de couleur des pixels respectifs, afin de former la carte de profondeur pour l'interface MCI. Dans une réalisation de l'invention, les valeurs de profondeur sont produites en ajustant et/ou en mettant à l'échelle les valeurs des pixels de la composante de chrome Cr de l'image couleur monoscopique du système couleur Y'CbCr.
